Don't forget that Troop 168 has a library! Many pamphlet titles are available to Scouts as they begin working on specific Merit Badges. Scouts simply need to sign the pamphlet out and return it when done.
Boy Scout Advancement Requirements Changes as posted on USScouts.org:
The Guide to Advancement - 2019 and 2020 Scouts BSA Requirements are the official Boy Scouts of America sources on Boy Scout advancement procedures.
When there is a conflict between two published lists of requirements, such as Scouts BSA Requirements (BSA Publication No. 33216) and a Merit Badge pamphlet or the Scouts BSA Handbook, the requirements book should normally be considered to be the controlling document, until a newer edition of Boy Scout Requirements is issued. However, the following excerpt from the Guide to Advancement- 2019 explains what to do when merit badge requirements change:
188.8.131.52 What to Do When Requirements Change
The current annual edition of Scouts BSA Requirements lists the official merit badge requirements. However, those requirements might not match those in the Scouts BSA Handbook, the merit badge pamphlets, and the requirements listed at www.scouting.org/meritbadges because the Scouts BSA Requirements book is updated on an annual basis.
When new or revised merit badge requirements appear in the Scouts BSA Requirements book, any Scout beginning work on a merit badge must use the requirements as stated therein. However, if changes to merit badge requirements are introduced in a revised merit badge pamphlet or at www.scouting.org/ meritbadges during the year after the Scouts BSA Requirements is released, then the Scout has through the end of that year to decide which set of requirements to use.
Once work has begun, the Scout may continue using the requirements he or she started with until completion of the badge. Alternatively, the Scout may choose to switch to the revised requirements. Sometimes, however— especially for more significant changes—the Scouts BSA Handbook, the Scouts BSA Requirements book, www. scouting.org/meritbadges, or official communications from the National Council may set forth a different procedure that must be used and may establish a date by when use of the old requirements must cease.
There is no time limit between starting and completing a badge, although a counselor may determine so much time has passed since any effort took place that the new requirements must be used.
