^ True enough...
Having worked professionally as a curator in art museums, and with visual art and artists, for going on 50 years - there is sometimes a tendency to apply in-perpetuity-museum-standards to private or personal preservation measures which is way out of proportion with anything the artifacts/objects truly require.
And it gets really really really expensive, really fast... so much so that even museums are not 100% able to maintain the perfect state of preservation controls for every artifact they protect. There is a kind of triage, so to speak, that comes into play when deciding how much to do for/with each artifact, based on its significance, without intentionally or negligently doing or allowing harm.
Sensible precautions are always in order for any collector or collection. For the average collector, framing or matting something at a place like Michael's (etc) using words such as "archival" or "acid-free" or "neutral pH" will suffice... but chances are the person helping at the counter will not have a clue what the words "lignin-free" relate to.
Suppliers like Talas, as mentioned above, or Gaylord, or University Products, or Hollinger always have the highest standard of product of course. They also offer many choices of ways to put neutral pH barriers into framing, matting or long-term storage projects. Yet, at this point in time, even Target, Amazon and office suppliers like Staples or Office Depot claim to offer what is probably more-than-less archival materials which are perfectly acceptable in most normal applications.
