Library collections

This table shows the comparative strengths of some of the major collections of alchemical books. This data has been extracted from my database which is essentially a union catalogue of the Ferguson, Young, Duveen, Wolfenbuttel and British Library collections, which lists at present 4678 books with 2810 unique works"... 

Once candidate hits have been identified, it is important to confirm the identity of the compounds, either by resupply (ifpossible) or resynthesis. It is not uncommon for compounds in large library collections to decompose, to be impure, or to be mislabeled (despite the guarantees often provided by commercial suppliers). 

Artephius, The Secret Book of Artephius," 12th century translation by Lapidus, The British Library Collection. 

Basil Valentine, The Triumphal Chariot of Antimony (Leipzig, 1604 English translation, 1660, The British Library Collection). 

Hermes-Trismegistos, Corpus Hermeticum, xlii, John Everard translated from Ficino s Latin, in the British Library Collection, London 1650. 

Approximately half of the documents in the site have been published in the Journal of Chemical Education where they are permanently archived, http //jchemed.chem.wisc.edu/JCEDLib/index.html. The JCE Digital Library Collection (JCE DLib) contains both peer reviewed and open access documents. Usage policy for these documents follows standard practice for JCE. Faculty may distribute copies of the documents to students in their classes if they have a JCE subscription or their campus has an IP based subscription to the Journal. Students have access to documents through a campus IP based subscription. 

Sulfite paper has a relatively short life span, since residual acid will continue to hydrolyze the cellulose and cause embrittlement. Further sources of acid include aluminum sulfate (which is added together with resin to suppress bleeding or feathering of ink into the paper) and S02 and NO from the atmosphere. Much of the world s library collections and archives will soon be lost as the paper crumbles. Various deacidification treatments (e.g., with ammonia, morpholine, cyclohexylamine carbamate, or diethyl-zinc) have been proposed and tried, but at best they can only halt the process of embrittlement and cannot reverse it.14 With the move to kraft pulping, alkaline peroxide bleaching, and increasing use of precipitated calcium carbonate as a filler, the high quality papers produced today are intrinsically acid free and should also resist subsequent acidification by S02-polluted air fairly well. 

The Free-Wilson approach has proven to be a successful strategy for the analysis of data sets where large library collections of compounds obtained through combinatorial chemistry have been screened against a panel of related proteins or target families, thus boosting the overall quest for selective inhibitors. 

Leather, vellum, and parchment are important materials in library collections. All three are made from the skin of animals.

The 27-MHz dielectric dryer was used initially to thaw all of the frozen office correspondence and file drawer materials. This was extremely valuable since quick access to these records was necessary for two reasons (1) getting the Museum operational as soon as possible and (2) establishing a sound basis for insurance claims on all property, including the glass and library collections. 

This is the abbreviated entry as catalogued according to the Anglo-American Cataloguing Rules (2nd ed.). It is included here because of its predominance in library collection records.

In recent years, much work has been devoted to the identification and interpretation of infra-red spectra by computer. Collections of spectra on paper can be converted into a numerical form (digitised) and recorded on a disk or tape, and many modem infrared spectrophotometers record the spectra directly in digital form. The use of a data station coupled to an infra-red spectrophotometer enables the spectrum to be matched automatically against those in the library collection, and the names of compounds giving the closest fit displayed. An indication of the closeness of fit may also be given. It is important that the identification is checked by a careful comparison of the spectrum with a printed copy of that of the compound(s) indicated. 

COMPOUND IDENTIFICATION The identification of a compoimd from its mass spectrum may be achieved by matching the spectrum against libraries of spectra. However, if the compound is not already known, e.g. a drug intermediate or an unknown metabolite which is not in the library collections, the fragmentation patten must be interpreted from first principles using as much other analytical information (UV, IR, NMR, etc.) as may be available.
