This is really good news:

Improved Article PDF Files

A new PDF format for downloading and printing articles has replaced the previous High Quality PDF format. This new format enables JSTOR users to “search” or “find” words and phrases within the PDF version of JSTOR articles, as well as copy and paste portions of text from them. In addition to these benefits, the new format facilitates the use of screen-reading software, such as JAWS for Windows. Moreover, PDF files in this new format are, on average, smaller in size than our current High Quality PDF files, which means that they can be downloaded more quickly and easily. We encourage you to try the new High Quality PDF files, especially if you have had printing or downloading difficulties in the past.

If – like me – you use JSTOR to download older articles, it’s fantastic news that the pdfs are now fully searchable (I had started to OCR the more important articles so that I could search them with Spotlight etc.).
