TLG will keep online instruction for how long?

[happymark]

Just wondering if TLG would keep all the instructions (.pdf) online?

or then would do some clean up (old sets instructions will be retired?)

I am asking this because I am thinking I might need to save the pdf locally.

All the instructions online at the Customer Service website now are the same ones that have been there since TLG first began hosting PDF instructions at the customer service website. And furthermore, instructions occasionally get added for long-discontinued sets (for instance, the instructions for 6236 King Kahuka were added only a year or so ago), so I don't think the age of the sets is an issue at all. Naturally, any number of unforeseeable things could happen involving the LEGO website, and I don't have any personal insight into how the LEGO Customer Service website is operated, but I don't think the site's PDF building instructions are going away any time in the foreseeable future.

Instructions elsewhere on LEGO.com (for instance, alternate model instructions on the LEGO Club website or the sites for individual LEGO themes) do get taken down after a certain amount of time passes (usually after the sets involved have been discontinued for quite a while), so those would be worth saving backups of. Although if there are instructions you want to see that have been removed from the site they were on, many can still be found using the Archive.org Wayback Machine.
