Traditionally, in print media, an index is compiled and put at the end of the publication. Modern digitization technology has enabled every word in the pdf file to be indexed. This enables one to search for a word or words in the entire file, which is very powerful and handy for the reader.
All the Theosophist and Lucifer files in this site are searchable pdf files. The credit goes to Marc who took care of the processing after scanned file was available.
Use the search feature and enjoy the magazines.
