International Catalogue of Scientific Literature

The Catalogue was produced by an international committee and was published by the Royal Society of London.

[2] According to Isadora Mudge in the Guide to Reference Books: "While issued this was the most important current bibliography covering all the sciences.

[4] As the Royal Society was unable to continue financially supporting the Catalogue, financial assistance was sought from the scientific offices of contributing countries.

[5] Despite these efforts, the Catalogue ceased publication in large part due to increasing international tension in the build up to World War I[6] and to a lesser extent the resulting devaluation of currency.

[7][8] As Mudge notes, the Catalogue "[i]ndexes a large number of important scientific journals, but was never very satisfactory for up-to-date reference work because of the delay in publication.
