Writer for Hire:
If my clients ask for offline sources, I use offline sources. It is simply a matter of asking for it in the first place. If I have to physically go to the library, though, expect to pay more than $20 per page. Such research takes far longer.
The days of going to the library and using the Dewey Decimal system to find out dated sources is becoming obsolete. The vast majority of offline sources also have online versions. Schools have enormous databases of professional, peer-reviewed journals and books
When first discussing this task, there was no mention of paying more than 20$ a page, rather than $25 a page, which is what I was quoted. Mr. Halasz had also told me before posting publicly here that he does not have access to offline sources before saying something different here, re: it would cost more. Besides, anyone who has experience with doing research for scholarly work knows full well that tertiary sources in the form of newspaper and magazine articles found online do not qualify as sources for scholarly research.
Yes, there are indeed published sources that are also found online in the books of e-books and e-journals, but not a majority of them, as is claimed, are available online, or are open access for that matter. In other sources, one needs to have access to a library to find them.
Hence, there is no complete substitute for library research, whether from one's computer anywhere or preferably on the library premises where the majority of scholarly resources are to be found. No longer going to the library therefore belongs to the realm of science fiction, and not common present reality.
It remains to be seen whether Mr. Halasz is going to be able to deliver the goods that I had paid for after telling me to wait for the next improved results and not post anything negative. I will gladly post a positive review if that is going to happen.
