"I thought I would share an update on my Dansco preservation project! I was privileged enough to attain a large part of David Lange's personal collection of Dansco albums. I almost have one of every Dansco album ever made [except for some one-off custom albums and the #7240 Cuba Typeset Album!] I now have around 500+ Dansco Albums and Folders. I am slowly making my way through to catalog each piece and researching their history. As I learn and catalog more, I will make sure to keep the E-Sylum readers in the loop!"

Congratulations on a great acquisition! -Editor

"I have a question regarding book preservation. We often have dozens if not hundreds of books in our collections. But what is the optimal environment for long-term preservation of our books? Specifically for coin albums like Dansco and Whitman?

"I have hundreds of Dansco albums and folders with many filled out. It's unclear what humidity is optimal to avoid books drying out. Or what temperature to maintain? If lighting should be considered? Or something else? My goal is to keep my albums safe and to avoid my coins toning."

We've covered this topic a few times, but it's complex with many aspects to cover. Because of the varying sub-topics, it's hard to locate earlier articles in our E-Sylum archive. I do recall Joel Orosz discussing some aspects of this, and a video tour of his library is linked below.

What advice do readers have for Justin? -Editor

"Traditionally, the recommendations for book storage has been 65 degrees Fahrenheit, with a relative humidity of 50%.

"Ultraviolet light is the culprit in fading books, so natural sunlight, fluorescent and compact lights should be avoided. Incandescent lighting was always recommended, but incandescent lights are now being phased out. I believe that LED lights are UV-free, but I'll defer to experts on this point."
