Reading: a few options
Here are some possibilities for you:
Digital: In your Read & Review folder, you can establish the habit of using helpful filenames. The goals are to be as concise as possible with the most useful information available. A format that works well is <date saved>-<initials of author>-topic.
E.G. My brother (P.D.W.) forwards me an FYI news article about a local event. I may enjoy reading it, but nothing would die or fall apart if I didn't. I tuck the contents away thusly:
101008-PDW-article re bridge rehab
By using the YYMMDD format in the filename, the newest stuff stays on top. When the folder gets too large for your comfort level, skim through the bottom and clearcut.
It takes very little time to store a file in this way, and it is very easy to find when needed. That said, you will find times that your interest in reading it is so low that you don't want to even create the file. In such cases, you may choose to archive the email within the email system itself in the off-chance you later want to retrieve it. Archive beats Delete for old emails if there is any chance you may need it.
Paper: in the case of journals you might want to refer to in the future, there is a "utility vs futility" balance between keeping enough information that it is useful and simultaneously keeping that information organized in a way that you can find what you need quickly enough (and also physical storage space and moving considerations).
You pointed out that it is rare that you actually go back and read articles from those sources. I can relate to this, as I carried around notes from college for years afterwards ("just in case I decide to brush up on..."). It can be very tempting/easy to keep accumulating this type of material, to the point of hoarding. Where to draw the line is a personal (and emotional) decision that may relate indirectly to a universal human fear of loss. In the end, I found that the Web almost always provided what I needed, and much faster.
Imagine a time that you would be looking for information.
a) Would you search the paper-based journals, open Google (which may lead you to the journal article anyway), search your computer, or search some other way?
b) How much effort is worth it to keep that information available in physical form? (This may relate to keeping it until you change offices, for example.)
c) Is there an online database of those journals, that you could search by topic, keyword, or full-text? (If your subscription allows for online back issue access, keeping old copies becomes less relevant.)
I have found that moving to digital storage of reference information offers enormous benefits overall (with the obvious disadvantage of not being able to just grab a book and go.) Full-text search, easier organization, multiple backups, availability of information (e.g. portable USB drive), and that more information no longer means more physical volume.
If you have very esoteric information on paper that would be hard to find elsewhere, a scanner with text recognition (ScanSnap, etc.) can turn a shelf of journals into full-text searchable PDF's in a day. In odd circumstances, like an odd pamphlet that I may want to read but don't want to take care of in case I never do, I snap a few photos with my phone or camera, and file it away into digital storage, using the format described above.
In all cases, it is very important to be sure to have properly processed the information, so that the Read & Review does not contain Project Support or Next Action items. It needs to all be FYI or, at most, slight-chance-of-possible-future-reference-value. Reading material that has a valid chance of future reference value goes into A-Z Reference folders by topic, with filenames as above.
