I have been publishing in the past with a certain abbreviation of my name which I am unsatisfied due to draconian rules in my previous institution which wrote my name in the following way: X. Y. Z. lastname2.
Being my name composed of the following nouns: firstname1 firstname2 lastname1 lastname2.
For new publications I wish to change it to another format such as X. Y. lastname1 lastname2.
I wonder about the impact it might have in my academic profile, this is, whether articles databases would fail to index correctly both of the publications to the same person.
I also wonder what other complications this change of my name abbreviations might carry.
