Title: No more than 100 characters, lacking jargon and abbreviations where possible.
A title should be the fewest possible words that accurately describe the content of the paper. Omit all waste words such as "A study of ...", " An Analysis of ...", "Observations on ...", etc. Indexing and abstracting services depend on the accuracy of the title, extracting from it keywords useful in cross-referencing and Internet searching. An improperly titled paper may never reach the audience for which it was intended, so be specific.
