Here are a few tips for obtaining quality medical material, without paying for it and without leaving your home.
1. Use google scholar, and search using technical words.
2. Search, and add pdf to the search. Most serious stuff is in pdf format
3. On google scholar, look around for the magic words "cited by" and 'similar articles". The cited by refers to more recent articles which have cited that article. This allows you to go forwards in time, to get more up to date.
4. Be aware that even though a version is often behind a pay barrier, if you look, you can find the same article posted elsewhere with free access.
5. When you really want an article, and you cannot get a free version, then
a. try another search engine.
b. google the names of the author. Sometimes they repost their article on an accessible site
c. email the author. They are often glad to send you a free copy
6. Use a VPN. Some articles are free in the USA for instance. This does not always work, but it worth a try
7. Some sites require signing up only if you are medical. Then get a friend who is medical to sign up and forward you the article. In some cases I have individually written to the site asking for access, and been accepted.
8. Learn to be relaxed about searching. Many times I have not been able to get through the pay barrier, but, I have found related articles which were similar/better.
9. Remember, the summary, the Abstract, is always free. The abstract is often enough. There is also a growing trend to include a plain language summary.
10. Wikipedia for medical matters is often surprisingly up to date and accurate. I understand that the medical pages can only be edited by qualified and approved writers, therefore, at least here, you can trust it.
