"This database is a completely revised new edition of the "Index Litteraturae Entomologicae : Serie I : Die Welt-Literatur über die gesamte Entomologie bis inclusive 1863" published by Walther Horn und Sigmund Schenkling in 1928-1929. The most important new features are:

• the original 25,229 citations (Horn & Schenkling 1928) have been increased to over 46,500; the extra data result from resolution of highly condensed original entries or are new;
• over 11,300 authors, artists, engravers, etc. have been recorded separately, thus supporting searches with various spellings of the name and connecting the bibliography with the biographies;
• over 10,300 journals, publishers etc., (called ‘sources’) have been recorded separately, thus supporting searches with various spellings of the title; dating information is included and titles are given in full;
• parts of works, other editions, addenda, translations, etc. were cross-referenced;
• Publication dates of the works have been revised based on secondary sources (see references);
• the citations can be exported in text format or BibTex format;
• users can comment on each citation and contribute to improving the database."
