CHEM 184/284 (Chemical Literature) - Huber - Winter 2022: Lecture 4

A two-credit course in the techniques and tools for effective searching the literature of chemistry, biochemistry, chemical engineering and related fields.

Introduction to Data Collections

Data Collections

Just as libraries can be organized by subject classification (grouping books on the shelf by subject area) or by indexing (creating records describing the book - author, title, subjects, etc. - and indexing the various types of information), so too, the primary scientific literature can be organized in two broad ways: indexing, or selecting data from the published literature and bringing them together in collections.  This lecture will look at the various forms of data collection.

  • These are a form of secondary literature in which an editor selects information from primary sources and arranges it to facilitate a particular type of access.
  • Often, the data are reviewed and evaluated by the editors before inclusion, adding further value.
  • The right data collection can be more useful than searching primary sources, depending on the objective of your search. If you're looking for a specific piece of data, or an introcution/overview of an area you are not yet expert in, data collections can save you a lot of time.

Types of data collections in chemistry

  • Dictionaries
    This includes both classical lists of definitions of terms, and "chemical dictionaries" which have alphabetical lists of compounds, with various kinds of data.
  • Encyclopedias
    Encyclopedias have substantial articles on relevant topics, usually in alphabetical order, usually with a significant bibliography of the source literature.
  • Physical data collections (including spectra collections, crystallography data)
    Physical data collections can take many different forms, depending on the objective of the editor. Some are ordered by compound name or formula, others by the value of the property in question.
  • Reaction and synthesis guides
    These may collect preparations of individual compounds, applications of individual reagents, or general methods, grouped by type of reaction, type of starting material or type of product.
  • Analytical methods guides
    These may deal with specific or general techniques, grouped by analyte, matrix, or method.
  • Health, safety, toxicity guides
  • Comprehensive works
    These are usually ongoing series, attempting to summarize all of a given area of chemistry. Good examples from the past include the Beilstein Handbook of Organic Chemistry and the Gmelin Handbook of Inorganic and Organometallic Chemistry.

 

Approaching a data collection for the first time: What should you know?

  • What type of data is it attempting to collect?
  • How comprehensive is it?  Is it attempting to collect all instances of, say, the melting point of naphthalene, or just a "best value"?  What years of the literature is it collecting from?  Is it updated periodically?
  • If it's a printed work (or a simple digitization of a print work), how is the data tabulated?  For an example, if you have a table of melting points, are tehy arranged alphabetically by substance name or numerically by melting point?  Different arrangements answer different types of questions!
  • How are tables grouped within the work?
  • Are there indexes?  If so, what are available: substance name (and does it include synonyms or not)? substance class?  CAS Registry Number? for substance data; for reactions, reactants? products? name reactions? reaction classes?
  • If it's an electronic database, what fields are indexed?  What are the display options?  Can you re-sort data? Can you export data to a spreadsheet?

Examples of Data Collections

Examples of Widely Used Data Collections in Chemistry

For greatest ease in visiing online subscription resources, log into the VPN or proxy server before returning to this page.

ChemSpider (http://www.chemspider.com/)

  • Created by Antony Williams, and now a product of the Royal Society of Chemistry, ChemSpider is a free website collecting a wide range of information on over 39 million (as of Jan. 2016) chemical substances, drawn from hundreds of data sources.
  • ChemSpider is seaerchable by names, formulas, properties and structures.  It is divided into three databases: Compounds (for molecular substances), Substances (includes salts, mixtures, formulations) and BioAssays (substance data seaerchable by keywords from bioassays of the substances.)
  • ChemSpider Synthetic Pages (http://cssp.chemspider.com/) is a related site for reaction data.

PubChem (https://pubchem.ncbi.nlm.nih.gov/)

  • PubChem is a free (taxpayer-supported) database created by the National Library of Medicine) containing name, structure, basic physical properties, safety, toxicity , drug and pharmacological information for millions of compounds.
  • It is composed of three separate, but linked, databases: Compound (covering single chemical comounds), Substance (including salts, mixtures and preparations) and BioAssay (for finding substances by terms describing their bioassays.)
  • PubChem now includes chemical toxicology information formerly contained in the Hazardous Substances Data Bank (HSDB) database.

CRC Handbook of Chemistry and Physics  http://hbcponline.com/ (print: QD 65 .H3)

  • Familiar source; published annually (currently in the 101st edition)  but usually changes little from one year to the next.
  • Variety of useful physical and chemical data, with some references. Tables are grouped in broad subject sections. Arrangement within tables varies.
  • Most frequently used for tables of organic compounds and inorganic compounds, which contain data on melting points, boiling points, density and solubility among others.
  • Note that both tables have synonym indexes following the table.
  • Not very systematic in choice of data, and indexing can be inconsistent.
  • CRC is now publishing a Web version of the Handbook as part of ChemNetBase at http://hbcponline.com//.
  • The electronic version may be browsed by table of contents, or searched by text term. It may also be searched by physical property values (requires a browser capable of handling Java 2 applets) and allows you to sort tabular information in a variety of ways. To use, select "Substance/Property Search", then pick the property or properties you wish to search by, then pick the appropriate operator (=, >, <, etc.), then enter the values you wish to search.
  • The electronic version may be searched freely by anyone, but display of data requires a subscription. The UC system has a current subscription to this version.

Merck Index https://www.rsc.org/Merck-Index/ (print: RS 356 .M4)

  • Published by Merck Pharmaceuticals, with data primarily on organics, strongest on drugs (surprise!).
  • Includes physical data, preparation references., toxicity and uses.
  • Arranged alphabetically by chemical name; well-indexed; updated irregularly.
  • It also contains a small number of other tables, and a section describing over 400 "name reactions" in chemistry, with reaction schemes and references.
  • The Merck Index is now available in a Web version from the Royal Society of Chemistry at http://www.rsc.org/Merck-Index/. The UC system now has a site license for the Web version. Compound information may be searched by chemical name, CAS Registry Number, selected property values and chemical structure. Name reactions may be browsed alphabetically or searched by keyword.

Millipore-Sigma (aka Sigma-Aldrich Catalog  https://www.sigmaaldrich.com/united-states.html (print: TP 202 .A48)

  • The primary purpose of the catalog is to faciliate ordering chemicals and other materials from Millipore Sigma. However, it also provides basic physical property data, Safety Data Sheets (SDS) and in some cases, spectral data on the chemicals they sell.
  • Note that in both print and online versions, a single compound may appear in a number of different product records, usually representing various grades of purity. Note also, physical property data is usually only listed for the highest grade version of a given compound.

  • /This version of the handbook can only be downloarded as a somplete PDF, not as individual chapters.

Other Electronic Data Collections

  • Many classic data collections are not available on the Web because their publishers are making good money off the print versions, and they haven't figured out how to best make money off of Web versions.
  • Consider searching UCSB Library Search or checking major collections of reference works (see the Indexes and Databases lists) as CRCnetBASE or Knovel.com
  • However, there are some good collections on the Web, mostly from government sources, academic sources, or commercial firms seeking to demonstrate the usefulness of their products.
  • In addition to sites mentioned above, see also UCSB Library's Chemistry & Biochemistry Help by Subject page at http://guides.library.ucsb.edu/chemistry for some examples.
